MANIFOLDING MACHINE Filed Jan. 8, 1931 4 Sheets-Sheet 4 h/ fizi ze [610CPatented Mar. 21, 1933 WILHELM RITZERFELD, OF BERLIN, GERMANYMLANIFOLDING MACHINE Application filed January 8', 1931, Serial No.507,540, and in Germany September 20, 1928.

The resent invention relates to an apparatus or sectionally'mainfolding, "mainly bookkeeping entries, from an original providedwith mirror script (reversed script) on to copy sheets, cards or thelike previously moistened with an evanescent coating of a readilyvolatile liquid (such as methylated spirit, ether or mixtures thereof).Previous-' 1y known imprinting machines for this purpose, have notbeenable to be introduced into small and medium sized businesses owing totheir expensive structure.

By the apparatus according to the present invention, a machine is.produced which is considerably cheaper and, notwithstanding 'ection itsintended purpose of effecting bookeeping in small and medium businesses.The apparatus consists essentially of a base- 2 plate on which thesheet, card or the like to be impressed is laid, and of an impressingroller, around which the originalprovided with mirror script is secured,movably mounted in levers. The impression is cf- 2 fected bydepressionof the impressing roller on the sheet to be impressed.

A further feature of the subject; of the invention consistsin thestructure of the moistenlng device. The moistening container is movablyand spring mounted in a slide, the slide itself can be displaced by"hand along two slide rods secured in the side walls of the machine.Moreover a contrivance is provided on the impresslng roller, by the aidofwhich after each impression the impressing roller and therewith theoriginal secured thereon can be advanced by the breadth of a line. For

this purpose, a ratchet wheel is fast with the 4 impressing roller, inwhich a pawl spri ng mounted 'on the side wall of the machine en'- gageson raising the impressing roller and advances same a given amountcorrespondmg to the breadth of a line. By laying back the pawl thiscontrivance can berendered inoperative and a linealready in position canbe impressed-as often as required.

In addition a contrivance isprovided by the aid of which the originalcan be adjusted exactly in the impressing position on being its simpleconstruction, fulfills without obmounted; .A mirror adjustable to suitthe direction of vision by the operator serves for. this purpose. By theaid of this mirror can easily be ascertained even before the beginningofeachnew operative run, which entry is then about to be impressed.

The sheet or card to be impressed is clamped on the baseplate .by meansof a clamp.

Constructional examples of the subject of the invention are illustratedon the accomapanying drawings, in which Fig. 1 is a front elevation ofthe apparatus.

Fig. 10 is an elevation and IFig. 11 is a plan of the dr'iveof the moistening device.- I l Referringmore particularly to Fi s. 1 and 2, 1 and 2 are side walls held toget erby a baseplate 3. In the baseplate 3, at theposition where theimpression isefi'ected, a recess 4 [is provided, which serves to receivea counter-pressing strip 5of elastic material, such as rubber. Theoriginal 6 bearing the mirror script is wrapped around a roller 7. Theroller .7 is rotatably mounted in two curved levers 8'; 9 and 10 are twosheet metal guide plates,which partially cover the roller 7 and are eachrockingly' mounted in two spring levers 11 and 12 on both sides of'therollerpressing levers 8. In the two guide plates 9 and 10 are mountedguide rollers 13 whi rovide a sure guidance for the originalGQ eyed onthe spindle of the roller is a ratchet wheel 14', in which engages aspring-in:

I fiuenced pawl 16 mounted on a carrier 15 provided on the side wall 2;The two rollerpresslng levers 8 are secured on a spindle 17,

- which can beangularly displaced by a crank 18. The rotation of thecrank l8 is limited rearwardly by an abutment stud 19. Amoisteningcontainer. is so mounted 1n 2. sl1de'21, that it can be heldin the position shown in Fig. 1 by the action of a spring.

The slide 21 slides on two slide rods 22 and 23,and is held in thestarting position by a tension member '24 gut cord or the like), WhlChled over guide sheaves '25 and 26 winds on a spring drum 27., Inside thespring drum- 27 is a spiral spring, by the action of which the slide 21together with the moistening' container 20 is constantly drawn back intothe osition of rest shown. 28 is a spring clamp, y means of which thesheet to be impressed is held firmly on the baseplate 3. This holdingdevice can be raised with the aid of a A lever 29. i

The mode of operation of the apparatus is as follows In order to'be ableto pass the original bearing the mirror script conveniently around theroller 7, the two guide'plates 9 and 10 are so thrust together that theysomewhat overlap and so to a certain extent form a continuous sleevewhich covers about half the circumference of the roller 7. By theparticular jointed mountin of the guide plates 9 and 10 in the small levers 11 and 12, it results that the plates in the closed togetherposition are somewhat raised from the impression roller. The sheetprovided with the original mlrror script can then be easily pushedthrough between'the roller and the guide plates. The guides plates arethen replaced by hand, whereupon the guide rollers 13 press the originalsheet against the roller 7.

The sheet to be im ressed is so secured on the impression plate y theclamping device 28 that the line to be impressed rests exactly on theelastic strip 5.

The moistening container 20 is then pressed by hand on to the sheet tobe impressed and simultaneously drawn over same. Having arrived at theend of the line to receive the 1mpression, the moistening container 20is released and is drawn back again into, the initial position bytheaction of the" spiral spring in the drum 27 with the aid of the mirrorscript of the original is dissolved and v transferred to the sheet to beimpressed. On

return. oi the roller 7, the'pawl 16 comes into engagement with theratchet wheel fast with the roller and turns same onwards an amountcorresponding to the distance apart of the lines of the original, sothat the next line comes into the impressing position.

A mirror 30 let into the basepla'te, enable the correct position forimpressing'to be at determine the entry now come to be impressed beforethe commencement of each new operative run.

In' the above described apparatus the various' operation, such asmoistening,-impressing, opening and closing of the card clamp areindividually successively effected by different separate actuations. Theap aratus 'can' however be so constructed that t e several operationsare effected in a single operation in an interdependent manner byactuation of a handle, lever or the like.

The card clamp in such case is automati-, cally opened and closed by therocking of the levers carrying the impressing roller.

On' depression of the impressing roller the moistening device issimultaneously drawn over the sheet to be impressed in such manner thatthe moistening of the sheet is t'erminated before the impressing rollerwith the lineto be impressed reaches the moistened section of the cardto receive the impression. On the outer side of one of the side walls ofthe apparatus there is for this purpose a cord drum, on which thetension the impressing roller, it is rotated by such spurwheels and thusdraws the moistening container over the card to receive the impres--sion. On return of the impressing roller the.

cord drum rotates in the reverse direction and the moistening containeris drawn back again into the initial position.

On the guide bar along which the moistening device slides, trippingdevices are pro- ,vided, which on the commencement of the moisteningoperation lower the moistening device on to the sheet to receive theimpression and after completed moist'oning raise it again automaticallyfrom'the now moistened card. These tripping devices can be adjustedalong the guide bar, so that cards of different widths can be moistened.In its initial position the moistening container projects with its lowerprotruding felt filling into an intermediate container, secured to theside wall and provided with a notch, which is likewise filled withabsorptive material and is saturated with readily volatile liquid fromonce found on mounting the original and to members, which lead over thesheaves to the ground spirit-tight) arranged above. Thus,

the filling of the moistener which wipes over the card sucks up liquidanew after eagl moistening excursion.

The device for advancing the impressing roller with the original securedthereon, the breadth of a line can be improved by the impressing rollerbeing connected by an adjustable cone with the ratchet wheel, in whichthe spring-pressed pawl pivoted behind me engages on raising theimpressing roller, nd advances same a given amount corresponding to thebreadth of a line. The cone can be drawn back by a small lever, so thatthe advance of the impressing roller is suspended and the line adjustedin position can be impressed several times in succession. Thiscontrivance is also of importance for the adjustment of the line of theoriginal tobe impressed, because with the cone withdrawn the impressingroller permits itself to be easily turned in its bearings, without theratchet wheel rotating therewith.

In order to ensure exact advance of the original-from line to line, anindicator is provided in the form of a spring-pressed ball which fromline to line snaps into recesses provided therefor in and for each toothof .the ratchet wheel and prevents inadvertent further movement of theimpressing. roller with the original stretched thereon, so that thelines to be impressed always positively arrive in the impressingposition.

The impressing roller itself can be provided with a pressing bar overwhich the original providedwith mirror script capable of impartingimpressions is looped. This pressing bar serves the purpose of ensuringa completely uniform pressing together of the line of the original to beimpressed with the card or the like to receive the impression resting onthe elastic base.

Moreover, on the levers or the like carrying the impressing roller, amovable paper support can be provided which prevents the originalhanging down behind and smudging the original script.

In order to ensure that the impressing roller, in whatever position itmay be, always assumes the same condition, i. e. the

pressing bar and thereby the line'of the original to be impressed alwaysis on the underside, the impressing roller can be rotatably mounted inbearer levers, which are pivotally connected to curved pressing leversfast on a spindle, whereby parallel guidance is effected. As the line tobe impressed, is in such case constantly directed downwards, the mirroris then arranged beneath the impressing roller.

In order to have a control as to whether and how often each line of theoriginal is impressed, a marking device isprovided on the' machine, bymeans of which each line impre'ssedis made known by an ink mark or thelike. This marking device is laterally aderal times can be marked in foreach impression. 1 4

The above described modifications of the subject of the invention areillustrated in Figs. 3 to 10. In these figures: 1 and 2 are a difierentplace side walls held together by a baseplate 3. In

the baseplate 3, at the position where the impression is effected, arecess is provided,

which serves to receive the counter-pressing justable in order that aline "impressed sev-' strip 5 of elastic material, such as rubber.

The original 6 bearing the mirror script is wrapped around theimpressing roller 7. On-

the underside of the impressing roller 7 a pressing bar 7 is provided,which is secured to two carrying levers 64. and therefore does notrotate with the roller 7. This pressing bar 7 has the purpose ofensuring com-,

. pletely uniform pressing together of the line the mirror scriptcapable of impressing might smudge. The ratchet wheel 14 is connected tothe spindle of the impressing roller by a come 62, which by means of ahand lever 63 alternatively can be either loosened or forced into theboss of the ratchet wheel 14, in order to couple same to the roller 7.The rollercarrying levers 64 are pivotally connected to the two curvedpressing levers 8 and 8 The pressing lever 8 is prolonged into a handle18, b means of which the entire apparatus can e operated. The impressingroller 7 is journalled in the roller-carrying levers 64:, which arepivoted at their rear ends to parallel guide levers 65, which in'turnare pivotally mounted on pedestal hearings on the counter-pressing plate3. A. parallel guidance of the impressing roller is thus pro- :vided,i.'e. the impressing roller always assumes the same angular situation inwhatever position it may be, the pressing bar and the line to beimpressed always pointing downwards. Underneath the impressing roller 7is arranged a mirror 67, in which the line of the original for the'timebeing on the pressing bar 7 is visible in correctly reading script, sothat the impression of the correct line and the adjustment of such linein the correctimpressing position can be controlled.

The card to receive the impression is changed or displaced.

Between the side walls l. and .2 there is a profiled rail 22 on whichthe moistener carriage 21 runs by means of rollers. The moistener 20 ispivotally mounted on the moistener carriage 21. The moistener 20projects iii the position of rest with its downwardly protruding felt orwick 20 filling into a notch of an intermediate container 21 which isconnected to a reservoir vessel 21. and likewise isfilledwith absorptivematerial (felt, cotton wool or the like). From .the moistener carriagelead tension members 34 (gut cords or the like), which are-secured toboth sides of the moistener carriage 21, over sheaves .36 to a two-partcord drum 35, on which these tension members are wound in oppositedirections. The cord'drum 35 is connected by a train of'spur-wheels tothe spindle 17 on which the pressing'levers 8 and 8 are fast. As shownin Fig. 10,,the

spur-wheel 37 keyed on the spindle 17 is not toothedthroughout itsentire periphery, but has a slipping surface 38, which corresponds witha slipping surface 49 on a spur-wheel 39.

The two spur-wheels 37 and 39 are so mutually set, that when theimpressing roller is depressed and the moistening container is in itsoutermost position against the side wall 2,

the transmission of rotation ceases, because at such instant theslippingsurface 38 and 40 interact. Only on raising the impressingroller 7 do the spurwheels 37 and 39 again come intomesh, and themoistener carriage travels back to its initial position only then whenthe impressing roller 7 can no longer obstruct it.- I

From the spur-wheel 39 the rotation of the spindle 17 is transmitted inthe usual manner by spur-wheels 41 and 42 to the cord drum 35. The corddrum 35 is of two-part construction, the two individual drums of whichare united by screws 44. As the screws 44 extend through slots43 intheouter drum of the cord drum 35, the relative positions of the twoindividual drums can be varied within limits after loosening the screws44, in order thereby to adjustthe tension of the tension members Themoistening container 20 automatically applies itself to the card toreceive the impression and on terminated moistening is automaticallyraised from the card. For this purpose trip devices are adjustablyarranged on the guiderail 22 and which serve both for appl i g l gmoistener and also for raising same, for enabling cards of differentwidth to be moistened and impressed. Fast with the moistening containeris an eccentric cam disc 23, Fig. 8, over which engages, in the raisedcondition of the moistener 20, a springinfluenced detent 24 which isprovided on the upper surface of the moistener'carriage 21,

clamped in the adjusted position along the guide rail 22 by a screwprovided with a lever 33. \Vhen'the moistening of the card to receivethe impression has terminated, a release 'pawl 26, pivotally mounted ona lever 25 connected to the moistener 20, encounters an abutment 29 on araising trip device 27, whereby the moistener 20 is raised. At the sameinstant the eccentric cam disc 23 frees the spring-influenced detent 24,and this now bolts the moistener 20 in the raised position. The raisingtrip device 27 can likewisebe [clamped fast at any desiredposition'along the guide rail 22 by a screw provided with a lever 30.During the return movement of the moistener carriage 21 thepawls26 and32 resiliently yield to the corresponding abutments, so that thus themoistener 20 remains in the raised position.

The line to be impressed on the original is provided with adistinguishing mark at each impression, so that there is a control as towhether and how often each line is impressed. In the side wall, 1, aspindle 5O ismounted on which a bearing block 51 is displaceably andsecurably mounted. A stem 52 is guided in the bearing block 51, andcarries at' its upper end a printing type 53 and at its lower end ispivotally connected to one arm of a rocking lever 54. On the other armof the lever 54 is a rearwardly yielding pawl 55, against which, onraising the impressin roller 7, strikes an abutment 56 provide 'on thespindle 17 and thereby so rocks the lever 54 that the type stem 52presses the type 53 against the line on the pressing bar 7 justimpressed. A tension spring 54 is connected to the lever 54 and aftereach marking draws the lever 54 and thereby the type stem 52 downwards.An inking pad 57 is mounted on the bearing block 51 above the-type 53,and is pressed by a spring 57 against the type 53. The carrier of. theinking pad 57 has a lug 58. On the type stem 52is a projection 59 whichon ascent of the type stem presses against the lug 58 on the inking padcarrier and thereby rocks the inking pad, so that the type stem canunhindered reach the impressed line of the original, v I The mode ofoperation of the above ,described apparatus is briefly as follows: I

The original for impartlng impressions is applied to the roller 7 withthe mirror script side outwards and the line to be impressed s0 adjustedthat it rests against the pressing bar 7 The card to receive theimpression is so slid beneath the then open card clamp 45, that the linewhich is to receive the impression comes to rest on the elasticcounterpressing strip. The handle 18 is then pressed down. Before theimpressing roller 7 has reached the card to receive the impression, themoistening container 20, after having yieldingly applied itself, byvirtue of the release trip device, against the card to receive theimpression, has passed along same. The impressing roller 7 then reachesthe moistened cardand the impression is effected. During the nowfollowing raising of the handle 18, the moistener container 20 travelsback in the raised condition to the initial position, the marking deviceis actuated and provides the just impressed line on the original with adistinguishing mark and simultaneously the card clamp 45 is again openedand the original is advanced by a line. The impressed card can now beexchanged or another line on the same card can be brought into theimpressing position, whereupon-the operations described are repeated.

By the provisionof several adjustable releaseand raising-trip devices,the card toreceive the impression can be moistened at discontinuouspositions along a line so as to receive impressions at givenpre-determined positions.
